  2. ANFO - Wikipedia

    en.wikipedia.org/wiki/ANFO

    The ANFO car bomb was adopted by the Provisional IRA in 1972 and, by 1973, the Troubles were consuming 21,000 kilograms (47,000 pounds) of ammonium nitrate for the majority of bombs. [15] The Ulster Volunteer Force (UVF) also made use of ANFO bombs, often mixing in gelignite as a booster, in the Dublin and Monaghan bombings of May 1974 which ...

    The fatal explosion involved at most a few tonnes of explosive. A larger explosion of about 80 tonnes of ammonium nitrate emulsion, ANE, an emulsion of ammonium nitrate, fuel and water, UN 3375) was caused by fires under storage facilities at the site at 11:02 AM. There were no fatalities in the second explosion because the site had been evacuated.

  4. Paint protection film - Wikipedia

    en.wikipedia.org/wiki/Paint_protection_film

    Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens ...

    Film an explosion at 50,000 frames per second. At the New Mexico Institute of Mining and Technology, Adam and Jamie loaded 855 pounds (388 kg) of ANFO into a recreational vehicle. They set off the charge and filmed the blast at 50,000 frames per second, five times the fastest rate they had previously used.

    Cellulose acetate is also known as "safety" film and started to replace nitrate film in still photography in the 1920s. [1] There are several types of acetate that were produced after 1925, which include diacetate (c. 1923 – c. 1955), acetate propionate (1927 – c. 1949), acetate butyrate (1936–present), and triacetate (c. 1950 – present).

  7. Anti-halation backing - Wikipedia

    en.wikipedia.org/wiki/Anti-halation_backing

    An anti-halation backing is a layer found in many photographic films—and almost all film intended for motion picture cameras—usually a coating on the back of the film base, though it is sometimes incorporated between the light-sensitive emulsion and the base. Its purpose is to absorb light that passes through the emulsion, thus preventing ...

  8. Surfactants in paint - Wikipedia

    en.wikipedia.org/wiki/Surfactants_in_paint

    Binders are the film forming component of a paint as it dries and affects the durability, gloss, and flexibility of the coating. Polyurethanes, polyesters, and acrylics are all examples of common binders. The solvent is the medium in which all other components of the paint are dissolved and evaporates away as the paint dries and cures. The ...

  9. Macroemulsion - Wikipedia

    en.wikipedia.org/wiki/Macroemulsion

    This type of emulsion is thermodynamically unstable, but can be stabilized for a period of time with applications of kinetic energy. [1] Surfactants (as the main emulsifiers ) are used to reduce the interfacial tension between the two phases, and induce macroemulsion stability for a useful amount of time.
